6.2.5 Influence of the Digital Input
Terminals upon FC Control Mode
The influence of the digital input terminals upon control of
the frequency converter can be programmed in
8-50 Coasting Select
to
8-56 Preset Reference Select
.
NOTE
Note the
8-01 Control Site
overrules the settings in
8-50 Coasting Select
to
8-56 Preset Reference Select
, and
Terminal 37
Coasting Stop (safe)
overrules any parameter.
Each digital input signal can be programmed to logic AND,
logic OR, or to have no relation to the corresponding bit in
the control word. This way, fieldbus only, fieldbus AND
Digital Input, or Ether Fieldbus OR Digital input terminal
can initiate a specific control command, that is stop/coast.
CAUTION
To control the frequency converter via EtherCAT, set
8-50 Coasting Select
to either
[1] Bus
, or to
[2] Logic AND
.
Then set
8-01 Control Site
to
[0] Digital and ctrl.word
or
[2]
control word only
.
More detailed information and examples of logical
relationship options are provided in
6.3 Control Profile
The frequency converter can be controlled according to
the DS 402 profile, or the Danfoss FC profile. Select the
desired control profile in
8-10 Control Word Profile
. The
choice of profile affects the control and status word only.
The desired control profile can also be controlled by object
6060 Modes of operation and readout by object 6061
Modes of operation display.Value -1 indicated FC profile.
Value 2 indicates DS 402 Velocity mode. ESI (xml) file has
default process data mapping for FC profile objects. If
drive is to be run in DS 402 profile the DS 402 profile must
be selected (e.g. by parameter 8-10 or object 6060) and
the according process data shall be configured. The easy
way to change the process data is to set the frequency
converter in the desired control profile and then the press
the "Load PDO info from device" button on the Process
data tab in TwinCAT. This ensures that the objects for
process data is matching the profile. In case of mismatch
between the selected control profile and the process data
objects, the drive will not enter state OPERATION but Error
PRE-OP and issue an abort code. See
and
6.5 Danfoss FC Control Profile
provide a detailed description of control and status data.
